Will this work with my existing X4 rear arm setup?

Yes — the upgrade kit is designed to integrate directly with the standard X4 rear arm, adding extra support without needing to replace your whole mounting system.

Do I need this upgrade kit for my tank?

Only if your tank has a rim or brace around the edges.

Is it difficult to install onto my current mount?

No — it’s a straightforward add-on. It bolts onto your existing setup and can be installed quickly without needing any complicated tools or changes to your tank.
